For what it is worth I have a 2010 105L Tabou Rocket and I agree with Sputnik, 20 knts is just about perfect for it.
I use the Rocket from about 17 knts up to 25 knts. Above 25 knts I switch to my Tabou 76L 3S as the Rocket starts to feel a bit big especially in open ocean chop and swell...
I weigh 65 kgs; so I would be classed a wafer (thanks 2035...

) as I would not use it in 30 knts.
P.S. In my Avatar I am using my Rocket with a 5.0 m2 sail in about 20 knts of wind - perfect!
